Current situation: two stents in RCA in February following unstable angina / 95% blockage in right coronary artery. two previous heart attacks / a stent each time in 2010 and 2021.
I'm currently on two blood pressure tablets (plus Bisoprolol 2.5mg): Lisinopril 20mg and Lercanidipine 10mg. I take the Lisinopril on a morning and the Lercanidipine on an evening. My blood pressure is controlled (though not always brilliantly) but I have a problem with the lercandipine as it can cause me to feel hot, have a flushed face and for a couple of hours, have a fast heart rate (in the high 70s and low 80s instead of the 60s). It basically was stopping me from going for a walk on an evening as my heart rate would be too fast and would take over an hour to come back down to anywhere near normal. I can't increase the lisinopril as I have had bad side effects on 30mg - I basically was barely urinating and was sweating profusely. When I went back down to 20mg everything went back to normal.
I had an appointment three weeks ago with the consultant cardiologist at the hospital. We discussed the above and he suggested that I replace the lisinopril with Candesartan and then when my blood pressure is well controlled, to come off the lercanidipine. He sent a leter to my GP suggesting I start on 4mg of Candesartan (the lowest dose). and to uptitrate the dosage as necessary depending on my blood pressure response and then to consider stopping the lercandipine. The consultant explained to me that what should happen is that I will start on 4mg of Candesartan. After two weeks my GP should then check my blood pressure, do any necessary blood tests and increase the dosage to 8mg and repeat this as necessary.
However, today I got a text from my pharmacist to inform me that my tablets were ready. As I wasn't expecting any _ phoned up to discover that there is a box of 4mg Candesartan for me to pick up. I then checked my online Patient Access account. My GP has stopped my Lisinopril and has instead prescibed 56 Candesartan 4mg tablets for me. I've had no advance warning, no phone call from the surgery to ask me to speak to the GP, no blood tests, nothing. Not even any instructions on what I should do next. Am I right in thinking my GP should have arranged to see me (via his receptionist phoning me?). It has taken me ages to get my blood pressure right and to be expected to go 56 days on the lowest dose of Candesartan could sent my blod pressure back up again. The equivalent dosage to 20mg of Lisinopril is 16g of Candesartan so taking 4mg of Candesartan would be the equivalent of taking 5mg of Lisinopril, a quarter of what i currently take. I worry I could end up having months of trying to get my blood pressure down again or worse (another heart related hospital admission) and it still doesn't address the problem of the Lercanidipne giving me a fast heart rate and flushing.
I feel like I should just contact the surgery and ask if i can just stick to what I'm currently taking. It's not great but it does keep my blood pressure OK. Plus some nights the Lercanidipine doesn't always cause problems and my heart is always as fast. the fast heart rate comes on about two hours after I take the lercanidipine and it does go away about two hours or so after that.
Apologies for the lengthy post. I'm very disappointed that my GP has just prescribed the replacement medication without making any arrangements to see me or to give me pointers on follow up treatment.
Has anyone else had a similar problem?
